New reports of soybean aphids have diminished during the last week, but one new location is worthy of mention. Tracy Cameron, DeBruce regional agronomist, reports that Kevin Rugaard, DeBruce manager at Corning, found soybean aphids in Taylor County (southwestern Iowa) on July 1. Tracy noted that the population was not anywhere near the economic threshold, but one plant had "about a 100 around the apical bud and stem area." Tracy has scouted many other fields in southwestern Iowa and has not found aphids at any other location.
